The differential chromaticity thresholds of three color stimuli have been determined from metameric matches carried out during the cone-plateau period after photopigment bleaching. The results are compared with some recently published ones [E. Hita, L. Jiménez del Barco, and J. Romero, J. Opt. Soc. Am. A 3, 1203 (1986)] obtained under similar experimental conditions but without prior photopigment bleaching. The possible effects of rod intrusion on color-prediction discrepancies are discussed in the light of both sets of results. Under our experimental conditions, with foveal fields of 3 deg, luminance within the low photopic level, and sets of primary colors produced by filters of differing spectral bandwidth, the rod intrusion effect can be ruled out as a possible cause of color-prediction discrepancies, although it does appear to produce variations in the sizes of the discrimination ellipses and in their orientation.
通过在光色素漂白后的视锥细胞平台期进行的同色异谱匹配，已确定了三种颜色刺激的色差阈值。将这些结果与最近发表的一些结果 [E. 希塔、L. 希门尼斯·德尔·巴尔科和 J. 罗梅罗，《美国光学学会志A辑》3, 1203 (1986)] 进行了比较，后者是在类似实验条件下但未事先进行光色素漂白时获得的。根据这两组结果讨论了视杆细胞干扰对颜色预测差异的可能影响。在我们的实验条件下，中央凹视野为3度，亮度处于低明视觉水平，由不同光谱带宽的滤光片产生的原色组中，视杆细胞干扰效应可以排除作为颜色预测差异的可能原因，尽管它似乎确实会使辨别椭圆的大小及其方向产生变化。
